Inbound Marketing Software for SaaS: Build Your Stack by Funnel Stage

Every "best inbound marketing software" article recommends the same ten tools. HubSpot. Semrush. Mailchimp. You've seen the list. Or more likely, you could get AI to write it for you.

The inbound marketing software we actually use at HowdyGo looks nothing like those lists. Some picks are well-known. Others you probably haven't come across. All of them earn their spot because we've used them, integrated them, or watched customers and peers get real results from them.

This guide is organized by funnel stage, bottom-up, and makes it clear at what stage of growth each tool starts making sense. We start with conversion tools and work backward to awareness. Getting your BOFU right first means every visitor you attract through content, SEO, or social has a better chance of converting. It's hard and expensive to earn clicks right now. If your bottom of funnel leaks, all the TOFU investment in the world won't fix your pipeline.

Why Trust This Guide

I'm Tom, co-founder of HowdyGo. I spend most of my time thinking about how B2B teams convert inbound traffic, and building the tools to make it happen. I also run a YouTube channel focused on SaaS product demos. Some of the tools in this article are what we run at HowdyGo. The rest are tools we've integrated with, or that we've seen customers and peers use to grow.

Quick comparison

BOFU: Convert and close

You spend money getting someone to your site. They poke around and leave. The gap between "interested" and "in your pipeline" is where most SaaS teams lose deals they never even knew existed.

HowdyGo: Interactive Product Demos

This is our tool, so take the recommendation accordingly. But we built it because we saw the same problem over and over: prospects wanted to try the product before talking to us, and the only options were a 14-day free trial (too much commitment) or a recorded video. Videos are a poor experience for the viewer. You're hitting play and pause trying to see what's on screen, and you don't walk away feeling like you actually understand the product.

HowdyGo lets you create interactive product demos from your actual product. An interactive demo is a clickable replica of your software that visitors can explore on their own. No signup, no call, no waiting. They click through real screens and get a feel for the product in two minutes. It works for marketing pages, outbound sequences, and sales follow-ups.

The numbers from teams using it: Flagsmith saw a 1.7x increase in signups after adding an interactive demo CTA to their homepage. Komo got a 30x increase in upsell requests by embedding demos in their onboarding flow.

If you're evaluating demo tools more broadly, we've written a full comparison of interactive demo software that covers the category.

Pricing: $159/mo for Starter with unlimited users and unlimited HTML demos. No per-seat charges.

Attio: CRM

Attio is the CRM we'd recommend to any SaaS team from seed to Series B. We built a HowdyGo integration with Attio and found the experience noticeably better than working with HubSpot's API. Where most CRMs force you into their data model, Attio lets you define your own objects and relationships. You build the CRM around how your business actually works, not the other way around. The interface is fast, and it stays out of your way.

Compare that with HubSpot, which advertises to plumbing businesses as much as it advertises to tech companies, and the way they approach their product feels like that too. Everything is a bolt-on: Marketing Hub, Sales Hub, Service Hub, Operations Hub. Each one a separate price, a separate learning curve, a separate billing line.

Pricing can also scale quickly once you start using multiple hubs or need higher contact tiers, which can make experimentation more expensive for growing teams. G2 reviewer

Where HubSpot still wins: the integration library is massive and enterprise features are deep. If you're at 200+ employees with a RevOps team running complex workflows, HubSpot or Salesforce might be the right call. For growing SaaS teams, Attio does the job without the overhead.

Pricing: Free for up to 3 users. Paid plans from $29/user/month.

Riverside: Content Creation Platform

Riverside bills itself as an AI-powered platform for recording, editing, repurposing, and distributing content. We use it specifically as a customer story engine.

Record a 30-minute interview with a customer. Riverside records locally on both sides, so audio and video quality is studio-grade regardless of internet connection. From that single conversation, you get:

• A case study video for your website
• Short clips you can run through OpusClip or CapCut for LinkedIn and social
• A podcast episode
• A transcript you can turn into a written case study

One conversation, four or five content assets.

This video was produced using Riverside to interview the founder and CapCut for editing:

For SaaS inbound, customer stories are the highest-trust content you can produce. Nobody believes your landing page copy. They believe a real person describing how they use your product. We made a video on how to create a SaaS case study if you want to see the full process.

We use AI here too. Claude can turn a Riverside transcript into a first draft of a written case study, pull out the key quotes, and suggest which moments would make good social clips.

Pricing: Free tier gives you 2 hours of recording at 720p. Paid plans start at $19/mo.

MOFU: Nurture and engage

Middle of the funnel is where leads decide whether you're worth their time. They've found you, they're vaguely interested, and now they're looking for reasons to keep going or drop off. These tools help you stay relevant without being annoying.

Loops: Email Marketing & Automation

If you're running email at a SaaS company using Mailchimp, ActiveCampaign, or a tool like Klaviyo that was built for e-commerce, Loops is worth a look.

It's built specifically for SaaS. The templates assume you're sending product updates, onboarding sequences, and changelog notifications, not promotional newsletters for a retail brand.

The API is clean, the docs are good, and it handles transactional email on every paid plan. No separate Mandrill subscription like Mailchimp forces on you.

We switched to Loops because our previous setup involved stitching together three different tools to do what Loops handles in one.

We use Claude to draft and iterate on email sequences before loading them into Loops. The straightforward template system means AI-drafted copy goes into production without reformatting.

Pricing: Free up to 1,000 contacts with 4,000 sends. That's enough for most B2B SaaS teams well into their Series A. Paid plans start at $49/mo with unlimited sends.

Mutiny: Website Personalization

Mutiny personalizes your website based on who's visiting. Different headlines for enterprise visitors vs. startups. Different CTAs for people arriving from a competitor comparison vs. an organic search.

When it works, it works well. The teams we've seen get the most from Mutiny have at least 10,000 monthly visitors and clear ICP segments they can target. Below that threshold, you don't have enough traffic to learn from, and the $1,000+/mo price tag is hard to justify.

If you're pre-scale, a simpler approach: run A/B tests with whatever tool you already have. Mutiny earns its keep when you're past the point of manual experimentation. Your CMS choice matters here too. If your CMS can't support dynamic content or custom components, even Mutiny won't save a rigid website.

Pricing: ~$1,000/mo. No public pricing, so you'll need to talk to sales.

Octolens: Brand Monitoring

Octolens monitors conversations about your brand and competitors across Reddit, X, LinkedIn, Hacker News, GitHub, YouTube, and 10+ other platforms. When someone mentions your category or asks a question you could answer, you know about it.

Where Octolens differs from enterprise social listening tools (the kind that cost $50K/year and require a dedicated analyst) is scope and price. It starts at roughly $89/mo and uses AI to filter noise, so you get alerts that actually matter rather than a firehose of mentions.

For any SaaS team, it gives you two things:

• Early intent signals. Someone asking "what's the best X?" on Reddit before they ever hit your site
• Competitive intelligence. What are people saying about your competitors that you could learn from

Pricing: Starts at ~$89/mo (Starter, daily updates). Pro ~$149/mo (hourly).

AI across the mid-funnel

We use Claude to draft nurture sequences, analyze which email subject lines perform, and personalize content for different segments. It's not a separate tool in the stack. It's the layer that makes Loops and your CRM more effective.

The practical version: take your best-performing email, ask Claude to write five variations targeting different pain points, test them, iterate. The feedback loop between AI-generated drafts and actual engagement data is where the value sits.

TOFU: Attract and discover

Top of the funnel is where most inbound marketing content focuses, but it shouldn't be where you start. We made a video on why SEO isn't dead for SaaS that covers why bottom-of-funnel content should come first and how TOFU fits into the bigger picture. The question with these tools is which ones are worth paying for and which ones you can replace with AI.

Semrush: SEO Platform

Semrush is the SEO tool most teams default to, and for good reason. The core functionality (keyword research, competitor analysis, site audits, rank tracking) is solid and well ahead of most alternatives.

What we use it for: tracking relative movements in visibility across search terms over time. You're looking for a general direction, not individual position changes. Google Search Console gives you the specifics and is generally more accurate for your own site. Semrush's value is in seeing where competitors rank and spotting keyword gaps.

At $139.95/mo for the Pro plan, you're paying for a lot of surface area you'll never touch. The content marketing toolkit, social media features, and PPC tools mostly collect dust. Their "AI visibility" feature feels half-baked, and the results aren't reliable enough to act on.

If you want something with fewer bells and whistles, SE Ranking is worth looking at. Solid core SEO features at a lower price point, without the overwhelming feature sprawl.

Pricing: $139.95/mo Pro, $249.95/mo Guru. 17% off on annual billing.

Surfer: Content Optimization

Surfer does one thing Semrush doesn't: real-time content optimization while you write. Give it a target keyword, it analyzes the top-ranking pages, and it scores your content based on term frequency, heading structure, and content depth.

We use Semrush for research and Surfer for execution. Semrush tells us what to write about. Surfer tells us whether we've covered it well enough to compete.

Alternatively, you can build a similar pipeline with Claude. Pull competitor content, analyze structure and coverage gaps, score your draft against them. We do this for some content. But Surfer's advantage is speed and consistency. It's already analyzed the SERP, so you don't have to set up the pipeline every time.

Pricing: $99/mo Essential, $219/mo Scale.

SparkToro: Audience Intelligence

SparkToro is audience intelligence, not social listening. Where Octolens tells you what people are saying about your category, SparkToro tells you where your audience spends time:

• Which podcasts they listen to
• Which publications they read
• Which social accounts they follow

That distinction matters. If you're an SaaS team trying to figure out where to invest your marketing effort beyond "SEO and hope," SparkToro helps you make that call with data instead of guesswork. Should you sponsor a podcast? Which one? Is your audience on Reddit or LinkedIn? SparkToro answers those questions.

Pricing: Free tier gives you 5 searches per month. Paid starts at $38/mo.

Pick a CMS that won't hold you back

Organic click-through rates are declining. AI Overviews are eating into search traffic. When someone does click through to your site, that visit has to count. And if your CMS fights you every time you want to embed an interactive demo, add a custom component, or build a page that doesn't look like every other template, you're wasting those hard-won visits.

The principle: your CMS should be natively extensible, have an API you can build on (including with AI and MCP tooling), and not block you from embedding interactive media or custom components. It should not be the bottleneck between your ideas and what visitors experience.

We use Payload CMS. It's open-source, API-first, and we can extend it with code whenever we need to. Other strong options:

• Ghost if you're content-heavy and want clean performance
• Framer if you care about design and want to move fast

Traditional CMS platforms are getting squeezed by tools like these that give you more control with less overhead.

AI in content creation

We write our content with Claude. Not as a "press button, get blog post" tool, but as a writing partner that makes the whole pipeline faster. Research synthesis, first-draft generation, editing passes, repurposing long-form content into social posts. This article went through that process, but every paragraph was specifically guided by a human with opinions.

The SaaS teams getting the most from AI in content aren't replacing writers. They're using AI to compress the research-to-draft timeline and spending their human time on the parts AI can't do well: original thinking, customer conversations, and editorial judgment.

Worth mentioning

Clay: Pipeline Automation & Enrichment

Clay sits between tools. It pulls data from your CRM, enrichment sources, and intent signals, then runs automated workflows based on what it finds. Think of it as the plumbing that connects Octolens' brand monitoring data, Semrush's keyword intelligence, and Attio's contact records into something actionable.

Worth flagging: some teams are starting to replace Clay with Claude and custom pipelines, especially those with engineering resources. Clay's credit-based pricing gets expensive at scale, and if you can build the enrichment workflow yourself, the cost savings are significant.

Even Anthropic themselves have used Clay for GTM workflows, which says something about the category's value, but the trend toward DIY automation is real.

Launch plan starts at $185/mo with 2,500 credits.

What we deliberately left out

Social scheduling. Sked Social (a HowdyGo customer), Buffer, Hootsuite, Later. All solid options. Social scheduling is a mature category and most tools do the job well. Pick the one that fits your workflow and focus your energy on what you post rather than which tool posts it.

HubSpot Marketing Hub. You already know about HubSpot. Every other list leads with it. It's a capable platform, but the pricing model and feature sprawl don't fit how most growing SaaS teams work. Check the G2 reviews if you want to see what mid-market teams actually say about the pricing.

Building your inbound stack

Not every team needs eleven tools. Here's what we'd recommend based on where you are.

Starter (cost ~$300-500/mo)

For a seed-stage team with one or two marketers:

• Attio (free). Your contacts and pipeline
• Loops (free up to 1K contacts). Onboarding and nurture emails
• Surfer ($99/mo). Optimize the content you write
• HowdyGo ($159/mo). Convert demo page visitors
• A CMS that keeps you moving, pick one that lets you get content out quickly and adapt as you figure out your growth strategy. Ghost, Framer, or Payload are all good starting points
• Claude, content creation, email drafting, research

Four paid tools, minimal overlap. Total cost under $300/mo if you're on free tiers for Attio and Loops.

Growth (cost ~$600-1,000/mo)

You've got traction and you're investing in content as a channel:

• Everything from Starter, plus:
• Semrush ($139.95/mo). Keyword research and competitive intelligence
• Riverside ($19/mo). Start producing customer story content
• SparkToro ($38/mo). Figure out where your audience hangs out beyond search

Still manageable for a small marketing team. We started with Semrush maybe a bit early, but it helped us scale our content strategy, and that choice contributed to over 250% year-over-year growth since we started HowdyGo.

Scale

You have enough traffic and pipeline to justify personalization and automation:

• Everything from Growth, plus:
• Mutiny (~$1,000/mo). Website personalization across ICP segments
• Clay ($185/mo) or custom Claude pipelines: enrichment and workflow automation
• Octolens (~$89/mo). Brand monitoring and intent signals

This is where the tools compound. Octolens surfaces signals, Clay (or Claude) enriches and routes them, Attio tracks the pipeline, and Mutiny personalizes the website for each segment. Don't jump here until the fundamentals are working.

Where to start

If you take one thing from this article: fix your bottom of funnel first. The best SEO strategy and the sharpest content won't matter if prospects land on your site and bounce because there's nothing to engage with.

An interactive demo on your highest-traffic pages is one of the fastest ways to turn visitors into pipeline. It gives prospects something to do instead of something to read.
